I am currently on clen and plan to use for 3 weeks and do eca for 3 weeks and cycle back and forth. I have been reading tons about caffeine and want to know if I can also add caffeine while on clen. I was thinking 200mg 3x per day. I dont have to worry about any extra I dont drink coffee or soda. Just want to supplement it to help burn unwanted fat. Im 26 6" 210lbs about 10-13%bf
